Description

Device for smoking a smokable material provided with a cover.

The present invention relates to the general field of devices for smoking a smokable material.

BACKGROUND OF THE INVENTION

Patent document WO2016022695 describes a device for smoking a smokable material comprising an upper assembly having a first recess for positioning smokable material therein and a first chimney open towards the inside of said first recess to collect therein smoke generated in this first recess by combustion of said smokable material, the upper assembly also comprising a top opening to evacuate heat from said upper assembly.

A combustible material is generally positioned above this high opening to heat the smokable material and generate smoke to be drawn through the first chimney.

It is common that after use, a blanking cover is positioned above the upper opening to cover it and thus block the combustion of the combustible material.

Such devices are for example known under the term water pipe or shisha.

It has been found that the flavor of the inhaled smoke depends on the heating temperature of the smokable material.

To ensure this flavor, the user must adjust the heating conditions by adding, removing or moving fuel relative to the smokable material. This requires many manipulations and many more or less precise tests before the user obtains the expected smoke flavor.

OBJECT OF THE INVENTION

An object of the present invention is to provide a device for smoking a smokable material making it possible to solve all or part of the aforementioned problems of the prior art.

To this end, the invention essentially relates to a device for smoking a smokable material comprising an upper assembly having a first recess for positioning smokable material therein and a first chimney open towards the inside of said first recess to collect therein smoke generated in this first recess by combustion of said smokable material, the upper assembly also comprising an upper opening to evacuate heat from said upper assembly and a cover for closing off this upper opening.

The device according to the invention is essentially characterized in that the closure cover comprises a plurality of flaps, each given flap of this plurality of flaps being movable between a position for limiting the upper opening (in which it limits the passage through the upper opening) and a release position of the upper opening (in which it frees the passage through the upper opening), these flaps being movable so that at least one of these flaps can be in the limiting position while at least one other of these flaps is in the release position.

Thanks to the invention, the user can act on each of the shutters in order to vary the conditions of heat evacuation via the upper opening.

The opening area located in front of a shutter placed in the limiting position will have a limited heat removal capacity.

A shutter placed in the limiting position also has the effect of reflecting the heat towards the upper opening and finally such a shutter makes it possible to increase the heat diffused towards the first recess and the smokable material which is there.

As will be seen later, the fact that some of the flaps can be in the limiting position while other of these flaps are in the release position allows the user to define the geometry of an air passage at the through the top opening.

Thanks to the invention, the user can also act on the way of oxygenating the heating material used to heat the smokable material.

It can thus arouse the combustion on a zone of the heating material by increasing the supply of oxygen there or on the contrary, it can minimize this combustion.

This allows better control of the parameters that influence the variation of the temperature of the smokable material, which ultimately allows the user to improve the flavor of the smoke drawn.

Preferably, the lid is arranged to adopt an opening limitation configuration in which all the flaps are in the limiting position and an opening release configuration in which all the flaps are in the release position.

In the limitation configuration, all the shutters are closed and the circulation of air is limited via the upper opening, which ultimately limits the supply of oxygen. The combustion is then slowed down and the heat better confined in the first recess of the upper assembly.

Conversely, the clearance configuration is useful when the user wishes to evacuate a lot of heat and thus limit the heating or cool the smokable material located in the first recess.

Other characteristics and advantages of the invention will emerge clearly from the description given of it below, by way of indication and in no way limiting, with reference to the appended drawings, in which:

DETAILED DESCRIPTION OF THE INVENTION

As illustrated in Figures 1a, 3, 5 and 6, the invention relates to a device 1 for smoking a smokable material 2 which comprises an upper assembly 10 which has a first recess 11 for positioning smokable material 2 therein and a first chimney 12 open towards the inside of said first recess 11 to collect therein smoke generated in this first recess 11 by combustion of said smokable material 2.

This upper assembly 10 also includes a top opening 13 to evacuate heat from said top assembly 10 and a closing cover 14 of this top opening 13.

In certain embodiments, such as that illustrated in FIG. 1a, the device may also comprise, in addition to this upper assembly 10, a sealed enclosure 21. The first chimney 12 is fluidly connected to this enclosure 21 of the device via a tube 22 The upper end of this tube 22 is removably connected to the first chimney and the lower end of this tube 22 opens into the sealed enclosure 21 and is immersed in a volume of liquid L placed in this enclosure 21 and serving of fume filtration liquid.

A second tube 23 is connected to this sealed enclosure 21 to allow the user to inhale, via this second tube 23, pre-filtered smoke located in the enclosure 21 above a high level of liquid L of filtration. The filtration liquid L is generally water.

This second tube 23 is deformable over at least a part of the tube 23 to allow the user to move one suction end of the tube 23 while the enclosure 21 remains stationary on a support.

The closing cover 14 comprises a plurality of flaps 15.

Each given flap 15 of this plurality of flaps is movable between a position of limitation of the upper opening 13, in which it limits the passage through the upper opening 13, and a release position of the upper opening 13, in which it releases the passage through the upper opening 13.

These flaps 15 are movable so that some of these flaps 15 can be in the limiting position while others of these flaps 15 are in the release position.

The user can thus choose the flaps 15 that he wants to place in the limiting position and the flaps 15 that he wants to place in the release position, each of these flaps being movable between its limitation and release positions independently of the position adopted by the other strands of the plurality of strands.

To this end, each given flap 15 of the plurality of flaps is pivotally mounted around an axis of rotation 15d dedicated to this given flap.

Each of the axes of rotation 15d dedicated to the flaps of the plurality of flaps extends in length in a plane common to these axes of rotation 15d.

In this case, this plane common to these axes is perpendicular to the central axis of symmetry 16 of said upper opening.

Furthermore, at least some of the flaps 15 of the plurality of flaps have a terminal end 15 extending outwards from the device 1 to form a shutter rotation stopper for the rest of the device 1.

Each 15th terminal end of a flap 15 forms a stop in rotation of this flap when this flap arrives in its position of release from the upper opening 13.

Each terminal end 15e of a flap 15 bears against a complementary surface facing outwards of a ring 20 of the device when this flap 15 arrives in its release position. This ring 20 of the device delimits a periphery of the second recess 17.

Each terminal end 15e of a flap 15 is formed between side edges 15a, 15b of this given flap. By pressing on a terminal end 15e of a given flap 15, the user exerts a rotational torque on the flap to move it towards its release position.

The lid 14 is arranged to adopt an opening limitation configuration 13, illustrated in Figures 1a, 1b, 4a and 7, in which all the flaps 15 are in the limiting position and an opening 13 release configuration, illustrated in Figures 2 and 3, in which all the flaps 15 are in the released position.

Each given flap 15 of the plurality of flaps has main side edges 15a, 15b which extend on either side of the flap 15, each of the flaps of the plurality of flaps being arranged between two adjacent flaps which belong to this same multiple panes. Thus the plurality of flaps form a succession of flaps extending over the entire length of a peripheral edge of the cover 14.

The side edges 15a, 15b of any pair of flaps adjacent to each other are brought close to each other and facing each other when the cover 14 is in the opening limitation configuration.

These same side edges 15a, 15b are distant from each other when the cover 14 is in the configuration of release from the opening (this distance is a relative distance compared to the rapprochement observed when the cover 14 is in the limiting configuration) .

The side edges 15a, 15b of any pair of flaps formed from two adjacent flaps between them of said plurality of flaps are spaced apart from each other by less than 2 millimeters, preferably by less than 1 mm when the cover is in the configuration opening limitation.

The more the space between the side edges 15a, 15b of adjacent flaps 15 in the limiting position is reduced, the more effective the function of limiting the upper opening 13 by the cover will be, thus improving the ability to control the flow of fluid via the opening and controlling the temperature of the smokable material 2.

Preferably, these flaps 15 are identical to each other, which facilitates the industrialization of the flaps of the cover 14.

Preferably, the cover has at least 6 identical flaps, ideally 6 flaps.

Thus, the user can decide to place two opposite flaps in the opening release position while leaving the other adjacent flaps in the limiting position so as to create a transverse air flow vis-à-vis the high opening. . Such an air flow is useful for fueling combustion.

With this embodiment, the user can also place all of the flaps placed on one side of the upper opening in the limiting position while the other flaps placed on the other side of this upper opening are in the release position. .

Thus, no transverse air flow is generated, which limits the supply of oxygen while allowing heat to be evacuated via half of the upper opening.

As understood from the various Figures 1a to 4a and 7, the side edges 15a, 15b of the flaps 15 of the plurality of flaps are straight and when the lid is in the opening limiting configuration, each of these side edges 15a, 15b extends radially with respect to a central axis 16 of the opening 13.

As illustrated in particular in Figures 1b, 4a and 7, the cover 14 is arranged so that when it is in its opening limitation configuration, it then defines a second chimney 17 which opens on one side towards the top opening 13 and on the other side towards the outside of the device 1.

In this case this second chimney 17 extends along the central axis 16 of the opening 13 which is an axis of symmetry of each of the first and second chimneys 12 and 17.

For the purpose of forming this second chimney 17, at least some of the flaps 15 of the plurality of flaps have a curved end 15c going towards the outside of the device 1.

Thus, said second chimney 17 is on the periphery delimited by all of the curved ends 15c of these flaps 15 placed in their limiting positions.

As illustrated by Figures 2, 3, 4a, the device 1 comprises a second recess 17 and a heat exchange wall 18 disposed between the first and second recesses 11, 17 to perform a heat exchange between these first and second recesses 11, 17.

The first chimney 12 opens directly into the first recess 11 while the upper opening 13 opens directly into the second recess 17.

The closing cover 14 of this high opening 13 is located above the second recess 17.

Thus, the heat exchange wall 18 constitutes a bottom of the second recess 17, this second recess 17 serving as a heating zone for, for example, burning therein a fuel such as coal while keeping this fuel away from the first recess. 11 receiving the smokable material. In the present case, the smokable material is in a capsule 32 of smokable material 2.

This capsule 32 has a wall in the shape of a revolution formed around a central axis of the capsule.

When this capsule is placed in the first recess, the central axis of the capsule then coincides with said central axis of symmetry 16.

The first recess 11 forms a bowl having positioning surfaces 11a arranged to be able to position a capsule 32 inside this first recess, this capsule 32 having a wall of shape complementary to the bowl and containing said smokable material.

The use of such a capsule makes it possible to preserve the qualities of the smokable material until the moment of its use.

The use of a capsule 32 also makes it possible to avoid having to handle the smokable material directly.

The use of such a capsule 32 is also advantageous for simplifying the cleaning of the first recess 11 after combustion of the smokable material (the capsule is simply removed from the first recess and it can be replaced by a new capsule). The device according to the invention greatly simplifies the experience for the user.

The device comprises at least a first air passage 28 connecting an external zone of the device to the second cavity 17 to admit air therein.

In this case, these are the first three fresh air passages 28 distributed around the periphery of the ring 20, these passages 28 being identical to each other and extending radially through this ring.

To allow the passage of air to the first cavity 11, the device also comprises at least one second air passage 29 connecting the first and second recesses 11, 17 to each other. Thus the air coming from the second recess 17 passes towards the first recess 11 after being heated there.

In this case, these are three second air passages 29 which each extend through the heat exchange wall 18. These three second passages 29 are here distributed at 120° from each other around the central axis 16. These second passages 29 are identical to each other.

In order for the air entering the first cavity 11 to be as free as possible from combustion fumes produced in the second cavity 17, these three second passages 29 are positioned in the immediate vicinity of the peripheral walls which respectively delimit the first and second recesses 11 , 17, that is to say in the immediate vicinity of the inner wall of the ring 20 which delimits the periphery of the second recess 17.

Preferably each second passage 29 is opposite one of the first passages 28 which corresponds to it. Thus, the air admitted to the first recess 11 is not mixed with the combustion smoke produced in the second recess 17.

Each first air passage 28 makes it possible to admit the air necessary for combustion into the second cavity 17 and the air which must come into contact with the smokable material placed in the first cavity 11.

Preferably, the heat exchange wall 18 supports peripheral perforators 30 oriented towards the inside of the first recess 11 and arranged to make peripheral perforations 31 through a wall 34 of the capsule 32 which contains the smokable material 2.

This capsule is of complementary shape to the first recess 11 in order to position it simply.

In this case, the capsule has the shape of a bowl, the bottom of which rises at its center to reach a level located above a quantity of smokable material placed in the capsule 2. This shape of a bowl is a shape of revolution.

The smokable material is thus shaped like a crown and extends around the center of the bottom of the bowl, the first chimney 12 opening into the first recess passing through the center of the bottom of the bowl.

Thus, the first chimney 12 is necessarily above a high level of the smokable material 2 which avoids a blockage of this first chimney 12.

When the capsule 32 is placed in the first recess, the center of the bowl bottom is in alignment with the axis 16 and the capsule can pivot freely with the heat exchange wall.

The heat exchange wall 18 comprises three peripheral perforators 30 spaced apart from each other at an angle of 120° around the central axis 16.

Each of these peripheral perforators 30 is arranged between two second air passages 29 so that when the device 1 is in its usage configuration with a perforated capsule inside the first recess 11, each peripheral perforation 31 of the capsule wall is remote from the second air passages 29 between which this peripheral perforation 31 is located.

It is sought here that the hot air admitted via a second air passage 29 is diffused in the first recess 11 by moving along the heat exchange wall 18 before coming into contact with the smokable material.

The heat exchange with the smokable material is thus more homogeneous and the risk of localized overheating of the smokable material which could affect the flavor of the smoke released is reduced.

This promotes more homogeneous combustion in the capsule.

As can be seen in FIGS. 3, 4a, 5 and 6, said heat exchange wall 18 carries at least one main perforator 19, one perforation end 19a of which is oriented in the direction of the first recess 11 in order to be able to perforate the capsule 32 there. and form therein at least one first opening for the circulation of hot air through the wall of the capsule 32 while this capsule 32 is positioned in the first recess 11 and bears against the said positioning surfaces 11a.

To facilitate the creation of this central perforation, the perforation end 19a has a sharp edge and extends in a bevel to better cut the capsule.

The main perforator 19 in the form of a tube having on the one hand a first end assembled with the heat exchange wall and on the other hand said perforation end 19a.

This main perforator 19 comprises at least one transverse opening 19b which opens into the first recess 11 and which is located closer to the first end of the main perforator 19 than to the perforation end 19a so as to form a air extending into the main punch 19 between said transverse opening 19b and the punch end 19a.

Thus, the main perforator 19 is in the form of a hollow needle open at its perforation end 19a to admit hot air into the capsule from an area external to the capsule which is placed in the first recess.

Ideally, this main/central perforator 19 emerges in front of the first chimney 12 to conduct there smoke generated by the smokable material present in the first cavity 11.

As understood in particular via Figures 1b, 2, and 3, the first recess 11 is formed in a first part 10a of the device, in this case this first part is made of silicone, and the second recess 17 is formed in a second part 10b of device 1 which includes heat exchange wall 18.

The heat exchange wall 18 is here screwed against one side of the ring 20 to define the second recess 17. The first air passages 28 are here formed via spaces between the ring 20 and the heat exchange wall 18 .

These first and second parts 10a, 10b are assembled together via an assembly mechanism selectively adopting a configuration for assembling these first and second parts 10a, 10b together (this assembly configuration is visible in FIGS. 1b and 2 ) and a disassembled configuration in which these first and second parts 10a, 10b can be moved away manually from each other (this disassembled configuration is visible in FIG. 4a).

This assembly mechanism is arranged to pass between the assembly configuration and the disassembled configuration by pivoting the second part 10b vis-à-vis the first part 10a.

To this end, as illustrated in Figures 3, 4a, 4b, the assembly mechanism comprises on the one hand three rods 24a, 24b, 24c which belong to the second part 10b and on the other hand three complementary parts 25a belonging to the first part 10a.

To limit the wear of the device during assembly or disassembly, these complementary parts 25 are metal inserts (here aluminum) which are placed / fit into complementary recesses 27 formed at the periphery of the part. silicone P1 which delimits the first chimney 12.

Alternatively, it would be possible to ensure that the silicone part P1 directly incorporates the shapes of these complementary parts.

As illustrated in FIGS. 4a and 4b, each of the complementary parts 25a has a perforation 25 into which one of said rods 24a, 24b, 24c can enter or exit by displacement of this rod in a direction parallel to said central axis 16 and parallel to an axis longitudinal of this rod.

Each perforation 25 is extended laterally by a slot 26 in which the rod 24a, 24b, 24c corresponding to this perforation 25 can slide only by rotational movement of the rod around the axis 16. Each slot 26 extends in length along an arc of a circle whose center passes through axis 16.

Each rod 24a, 24b, 24c is shaped so that when it is in the slot 26 which corresponds to it, its extraction from this slot by axial displacement in a direction parallel to the axis 16 is then prohibited. Thus, by pivoting the second part 10b relative to the first part 10a, to move the rods 24a, 24b, 24c towards the corresponding slots 26, the locking mechanism is passed from its disassembled configuration to its assembly configuration and thus assembles the first and second parts 10a, 10B to each other.

By pivoting the second part 10b with respect to the first part 10a, to move the rods 24a, 24b, 24c along the slots 26 towards the perforations 25, the locking mechanism is moved from its assembled configuration to its disassembled configuration. to thus allow the separation of the first and second parts 10a, 10b from each other by displacement of the first part 10a in the direction parallel to the axis 16.

Each of the rods 24a, 24b, 24c forms a foot of the second part 10b which makes it possible to place this second part 10b on a table while preventing the main perforator 19 or the peripheral perforators from coming into contact with this table.

Thus, the rods 24a, 24b, 24c make it possible to protect the main perforator 19. By positioning themselves in the perforations, these rods also serve as a guide for the assembly of the first and second parts 10, 10b. This facilitates the centering of the main perforator 19 vis-à-vis the capsule 32 located in the first recess 11 to perforate it properly.

As indicated previously, the first part 10a of the device in which the first recess 11 and the first chimney 12 is formed is preferably made of silicone.

Silicone has the advantage of resisting heat while remaining deformable so as to improve the seal between the heat exchange wall 18 and the wall in which the first recess 11 is formed.

Furthermore, as illustrated in Figure 1, the fact that the first chimney 12 is formed in a silicone part (the first chimney belongs to the first part 10a), allows an elastic deformation of this first chimney which makes it adaptable from sealed manner at the upper end of a tube 22 of the device 1.

Furthermore, the second part 10b of the device 1 which comprises said heat exchange wall 18 and the ring 20 which delimits the periphery of the second recess 17 are preferably made of a metallic material whose melting point is greater than 600°C.

In this case the heat exchange wall 18 and the ring 20 which together delimit the second recess 17 are made of aluminium. The hottest zone of the device, that is to say the second part 10b is in a material resistant to high temperatures (the shutters are preferably in this same material) while the first part 10a of the device which is far from the second recess 17 and high temperatures is in a material less resistant to heat but having more flexibility.
